Looks good, Write, but after some discussion we've decided to ask you to add in these two things: 

First, things that have moving/internal parts such as bodies and mechanisms are too complicated to draw in battle and as such shouldn't be possible in the heat of combat, so things such as a gun which involve many internal parts should not be drawable in battle. However, it should still be possible for her to draw one outside battle.  

Second, The more detailed a drawing is, the more powerful the created object is.
